RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92W) PREVIOUSLY LOCATED NEAR 
28.3N 152.9E IS NOW LOCATED NEAR 32.1N 157.1E, APPROXIMATELY 944 NM EAST-
NORTHEAST OF IWO TO. THIS SYSTEM IS CURRENTLY CLASSIFIED AS A SUBTROPICAL 
CYCLONE, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL AND MIDLATITUDE 
CYCLONE FEATURES. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY DEPICTS A 
SLIGHTLY ELONGATED LOW-LEVEL CIRCULATION CENTER (LLCC) THAT IS 
SUBTROPICAL IN NATURE WITH CONVECTION DISPLACED POLEWARD AND EASTWARD OF 
THE LLCC. A 132247Z ASCAT METOP-B IMAGE REVEALS 30-35 KNOT WINDS ISOLATED 
TO THE EASTERN SEMICIRCLE OF THE INCREASINGLY ELONGATED CIRCULATION. 
ENVIRONMENTAL ANALYSIS INDICATES MARGINALLY FAVORABLE CONDITIONS WITH 
STRONG POLEWARD OUTFLOW AND WARM (27-28 C) SEA SURFACE TEMPERATURES. 
HOWEVER, HIGH (25-30 KTS) VERTICAL WIND SHEAR AND DRY AIR ENTRAINMENT IS 
WORKING AGAINST THE SYSTEM. THE PROBABILITY OF TROPICAL TRANSITION IS 
ASSESSED AS LOW AS THE SYSTEM IS EXPECTED TO CONTINUE TRACKING 
NORTHEASTWARD AND QUICKLY BECOME EMBEDDED IN THE UPPER-LEVEL JET. FOR 
HAZARDS AND WARNINGS, REFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH 
WINDS AND SEAS PRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST 
AUTHORITY. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 30 TO 35 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS REMAINS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
